Economic Sensitivity Impact: Fluctuations in the overall economy, particularly industrial production and consumer spending, can significantly reduce shipping volumes and freight rates, directly impacting JBHT's revenue and profitability.

Fuel Price Volatility Challenge: Significant and sustained increases in fuel prices, or extreme volatility, can raise operating costs substantially, eroding profit margins despite fuel surcharge mechanisms.

Driver Shortage Pressure: An ongoing and worsening shortage of qualified commercial truck drivers can lead to increased labor costs, difficulty in expanding capacity, and challenges in meeting customer demand efficiently.
